"It sucks that it's a possibility of it being the end," he said last month. "We all hate it. You look at the [audience] numbers and you can only imagine what Fox is feeling."

Fringe is handing us a new mystery to unravel as its fourth season winds down: What’s with all the new agents?!

Australian actress Georgina Haig, known down under for her roles in The Elephant Princess and Underbelly, has been cast in the potentially recurring role of Etta, a new Fringe agent who turns up in this season’s 19th episode. (Season 4 resumes March 23 with Episode 15.)

Etta is the partner of the new male agent to be played by Lost‘s Henry Ian Cusick.

It remains unclear if Haig and Cusick’s alter egos will be working “over here” or “over there.” (The original breakdowns described their characters as “Alternate Universe Agents,” but Cusick’s G-man was later described as an agent of the FBI, an organization that doesn’t exist “over there.” Confused? Join the club!)

Making things more complicated, the buzz is that Haig’s role has more long-term potential than the one filled by Cusick(who is currently attached to ABC’s midseason drama Scandal).

-Lost star Rebecca Mader has won a guest role on Fringe.

The actress will appear in the final two episodes of the Fox drama's fourth season, reports TV Guide.

Her character Jessica is linked to villain David Robert Jones (Jared Harris) and will also share an "emotional connection" with Olivia (Anna Torv).

"The finale in many ways is our characters' final battle," explained show exec Joel Wyman. "[Olivia and Jessica] may find out they have more in common then they first thought."

Since Lost concluded in 2010, Mader has appeared on ABC's No Ordinary Family and short-lived sitcom Work It.

While the very real future of Fox’s Fringe still hangs in the balance, the network has let slip with a handful of episodic photos from the annually “out there” Episode 19, which this time around is titled “Letters of Transit.”

The title is of course a nod to the (fictional) documents that drive the narrative of the 1942 cinematic classic Casablanca, papers that ostensibly allow a person to travel freely and without question during World War II.

As gleaned from these photo captions if not the pics themselves, it seems that Walter will A) come to believe he has brain damage, B) get an injection to treat the condition and C) get help from an Old Nina along the way. And while the actor is not ID’d in the first image, it kinda looks like guest star Henry Ian Cusick, no?

As previously reported by TVLine, Lost alum Cusick and Aussie blonde Georgina Haig appear in the installment as FBI agents (the latter of which has been ID’d in pap pics as “Young Olivia”), Blair Brown has teased the introduction of “another Nina” and John Noble told us he got to play two new Walters in the installment. Meanwhile, two teaser videos (seen here and here) suggest we’ll be taking a look at an Orwellian future or reality well-populated by Observers.
